This month, photos of the interior of the Harley-Davidson factory were released online, featuring the new CVO Road Glide and CVO Street Glide Anniversary models.

Looking at the photographs, you can see the displacement of these limited-edition CVO (Custom Vehicle Operations) models: 121 cubic inches, equivalent to 1,983 cc. Also noticeable is the use of inverted forks with Brembo radial brakes and an adjustable windshield.
However, in the photographs we can see another, even more interesting detail: the camshaft cover has an unusual shape and an inscription that seems to indicate VVT, or Variable Valve Timing.

What is variable distribution?
Although we'll discuss this in more depth in a future technical article, variable valve timing essentially involves modifying the relative position of the cams relative to the camshaft, thereby achieving different torque, power, valve overlap, and compression profiles. It's like having multiple camshafts mounted on the motorcycle at the same time, and being able to select each one based on the circumstances or needs.

Harley-Davidson already offers VVT on its Revolution Max models, such as the Pan America and Sportster S, but this would be the first time this technology has been used on a Big Twin. Although this system offers technical advantages, such as different riding modes (sport, rain, ECO, etc.), these devices are generally adopted to maintain compliance with emissions regulations, something that is increasingly difficult for traditional HD engines.
Reverse?
Another significant change can be seen in the gearbox cover, which has different dimensions and shape compared to the traditional M8 model, which could suggest some internal changes to the transmission, such as the reverse gear.

We'll be keeping an eye on all these new features, which will likely also be applied to the conventional 2024 Milwaukee Eight models, which will be introduced after this summer.
